Hi guys,
I found this image in Google Image. Can anyone help me to set such a scene? My problem is its background. Whether it is just a simple backplate or there is a plane laid under the objects?

Try adding a "Background Ramp" using Edit > Add Geometry.  Or a simple ground plane, same drill, and a vertical plane with your backplate on it.  I've had a lot of success using frosted glass as the ground material, adjusting the roughness to draw out the reflections.

The ground plane is an anisotropic material with a dark colour and a roughness in first direction plus a tiny one in the second.

You'll see the two light stripes reflecting on the metal caps, so you can create a simple environment with two rectangular pins and perhaps a third one in the back.

The background should be a backplane image.

Maybe you can share your scene?

Anytime I've achieved something like this I've done what Bill suggested and used a background ramp. I'd model my own in this case with a tighter (smaller diameter transition) between the horizontal and vertical parts.

I see no reason to apply an anisotropic material to it. I think you'd have better results with a plastic/paint material. The reflections in the bottles suggest that a 2 or 3 panels straight HDRI from the KS library wold work. Then for the gradient behind the bottles, I'd use an IES profile and point it at the backdrop (rather than the bottles). With a little vignette, you'd be all set I believe.

Alright. I wanted to test out an idea with this one and found some better results than my first suggestion.

Attached is the result I got as well as the .KSP for you to download and use to learn from.

The solution I landed on was using a solid color background. Use the ground material applied to a backdrop ramp I modeled. The vignette was created using a jpg I created in Photoshop and applied as a backplate (suggestion of Richard Funnell's). I did this after applying a color gradient texture to simulate the vignette on a piece of geometry as the backplate. Issue there was the light from the HDRI was being blocked by the backdrop ramp, which is why ultimately I changed that to a ground material. This offers some nice rim lighting on the bottles. Lastly, I colorized the HDRI slightly to offer some more blue to simulate global illumination from the background color.

Lots of little tricks in here, but in concept, it's very simple and easy to reproduce. Hopefully this helps you. To reduce the noise in my rendering, I could have adjusted samples and render settings, but didn't have time to dial those in.

Cheers,
